[mythtv-users] Audio (buffering?) problems when in EPG, exiting EPG

[Steve]

I've got a problem with stuttering audio when I switch into the EPG when
watching live tv. There's also a visible artifact at the bottom of the
video preview window. The preview plays normally, but a black band
extends from the bottom of it, partially covering the clock.

Wierd thing is: when I switch to a virtual console and then back, the
problem dissapears. audio is back to normal and the preview works fine.
However, when I exit the EPG and go back to watching live tv the audio
stuutter comes back. Switching VCs again fixes the problem.

Anyone else seeing this? Any suggestions?
